Just two weeks after the 2013 Freret Street Festival drew record-setting crowds, Dat Dog, The Other Bar and Gasa Gasa will be hosting another festival Saturday evening, “Uptown Sounds,” featuring acoustic sets, DJs and full bands. The festival runs from 9 p.m. to 1:30 a.m. and will also feature art and film, and is being organized by Loyola University’s Music Industries Studies program, according to a post at The New Freret website.
